IMPROVEMENT IN PESSARIES.

TO ALL WHOM IT MAY CONCERN;

i Be it kno-.wn that I, ERNST F..H01`MANN, M. D., of Poughkeepsie, in the county of Dutchess, and State oi' New York, have invented a new and improved Pesse-ry; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure I represents a plan or top view of this invention.

Figure 2 is a transverse section of" the same.

Figure 3 is a rear elevation of the same.

Similar letters of reference indicate corresponding parts.

This invention relates toa pessary which contracts downward all round, and tits the entire neck of the uterus, anterior, posterior, and lateral, as far up as said uterus extends into the vagina, the posterior surface of the pessary being made to iit the convoxity of' the sacral vertebrae, and its anterior surface to the neck of the bladder, so as to give to these parts protection from pressure. An elevation on the upper surface supports the calde-suc, and at inclined surfaces on the sides keep the pessary in position and prevent any undue lateral motion of the same.

A represents my pessary, which may be made of hard India rubber or any other suitable material. The lower part of said pcssary'is'considerably smaller than its upper part, giving to the same the forni of a wedge, and it is so shaped that it fits -the entire nook of the uterus all round. An opening, a, in the centre of my pessary, serves to receive the neck of the uterus, and its concave posterior surface b tits the convexity of the sacral vertebrae, while its anterior concave surface c gives protection to the neck of the bladder in the same manner as the posterior surface gives protection to the rectum from pressure. A. shoulder or elevation, d, on the upper surface serves to support the cuZ-fZ-Sac, and flat retreating surfaces c, on both sides of the anterior concave surface c, keep the pessary in positionand prevent any undue lateral motion. By these means a possary is obtained which obviatcs the disadvantages of pessaries of the ordinary form or construction, and which can be used with great advantage and without inconvenience. It actually resembles in its form a pelvis.

What I claim as new, and desire to secure by Letters Patent, is-

A pessary made wedge-shaped and provided with concave surfaces 5 c, an elevation, d, and flat retreating surfaces e, substantially' as and for the purposes set forth.
